YUM Giving “Cannot retrieve metalink for repository: epel” Error

Purpose

In our base CentOS 6.3 image it uses a few endpoints in the EPEL repos that are set by default that use SSL 3.0. Due to this you will receive the error noted below when attempting to use yum update from the instance. This article will show you how to remedy that while we work on deploying an updated CentOS 6.x image.
